Predator 2 has a xenomorph skull in it but we don't call it an Alien film because its part of the Predator franchise. Alien has a space jockey corpse in the film even though the film is clearly not about space jockeys.

With that logic, you can't call Prometheus an Alien film just because there is a dead space jockey in the movie. If it's about jockeys, then its also the beginning of a new franchise and/or stand-alone film.

...the thing is, Scott started it in the first place, and he DID say it would be a prequel "set 30 years before Alien" to quote his words ...personally after seeing Robin Hood, I've lost all interest anyway

There is your logic right there.

No ones calling it an Alien film. It clearly is not. It apparently has links to the franchise of which we are fans and may provide back story's. That's enough for me to be interested.

The pilots ship was responsible for 2 full length tales about the Alien. I'd say it holds a little more weight than "dead stuff was in it"
